CENTRIFUGAL SEPARATO R.

SPECIFICATION forming part of Letters Patent N0. 706,087, dated August 5,1902.

` Application filed July 14, 1900.

To all whom, t may concern:

Be it known that I, HERBERT McConNACK, a citizen of the United States of America, and a resident otZVVestchester,v in the county of Chesterpand State of Pennsylvania, have invented certain new and useful Improvements in Centrifugal Separators, of which the following is a'speciflcation.

My invention relates to centrifugal liquidseparators, and more particularly to dividing the liquid-space of the rotary separator vessel by means of .inserted partitions, so asto facilitatethe separation of the constituent. parts of the liquid, commonly cream and skim-milk'.

The main object of my invention isr to form in the vessel a number or" complete separating-compartments,' each one of which will be in skim-milk communication with a compartment located at a greaterY distance from the center of rotation and also in cream communication with another compartment located nearer said center, and the said cornmunicating compartments forming jointly continuous passage-ways between the outer and inner Walls of the liquid for inwardly and outwardly flowing streams of cream and skim-milk, respectively, to which oppositelyflowing streams each compartment adds its contribution of each constituent. This I accomplish in a simple and eifective manner, which is fully described in connection with the accompanying drawings, which show a preferred construction embodying my invention, the novel features of which are particularly pointed out in the claims.

Figure 1 is a sectional elevationofa separator vessel having myimprovements applied thereto, the section being taken on the line fr a; of Fig. 2. Fig. 2 is a cross-sectional view taken on the line y y of Fig. l. Figs. 3, 4, and 5 indicate some modifications of the preferred construction.

A represents an ordinary cylindrical separator vessel having any suitable inlet, as ct, for the milk, outlets b and c in the closed end A' of the vessel for the cream and skim-milk, respectively, and any suitable closllre for the open end of the vessel, comprising, as shown, a cap-piece B, adapted to engage or disengage flange-like projections A' on the vessel, and a joint-plate C, with means for pressing the latter to its seat, though any preferred conserial No. 23,587. (No model.)

struction may be employed for the ends of the vessel without alfectin g my presentinvention.

The division-plates in my improved construction are preferably made up in the form of polygonal partitions or hollow prisms E E E2, adapted to lit one within the other, as indicated in Fig. 2, the angular edges cof eachprismatic partition being, as show n, in contact with a side of the adjacent outer partition, thereby forming two or moreconcentric circular series of compartments extending lengthwise of the bowl-each compartment of which overlaps adjacent compartlnents respectively nearer to and farther from the center of rotation. "Each'of these overlapping compartments is adapted to serve as a separate 'separating-chamber, receiving a supply of milk from the inlet space or cham- 'ber d and delivering the separated constituents respectively into outer and inner overlapping partitions through skim-milk apertures f and cream-apertures g, located reered to it from the communicating compartments, to whose `volume it adds en passant the respective amounts of skim-milk and cream separated in such compartment. Referring to Fig. 2, the series of communieating compartments l, 2, 3, 4, and 5 jointly form a double passage-way between the inner and outer walls of the liquid operated on for the currents of skim-milk and cream, (respectively indicated by the different dotted IOD . described.

of the series, as l to 5, thus serving also as an inlet to said outer compartment, while the cream-outlets g are at the nearest convenient point to the center of rotation to discharge into the adjoining inner compartment of said series.

In the modified construction indicated in Fig. 3 the form of the separating-compartments 9 and l0 is substantially triangular, as shown in Fig. 2, cylindrical partitions, however, E4, being arranged alternately with the polygonal or prismatic partitions already In Fig. 4. the walls of the partitions are represented as longitudinally corrugated, so as to form compartments 1l of slightly different cross-section, but obviously similar in effect. In Fig. 5 the compartments 2, formed between the eccentric or spiral faces of the partition, have the milk-outlets j" located at one end, as it were, of the compartment and the cream-outlet g' at the other end, which latter, it willbe seen, is nearer the center of rotation. The separation taking place in each compartment and the movement of the cumulated products therethrough is the same as already described. Other modiiications may be readily devised.

What I claim isl. In a centrifugal liquid-separator, two or more vertical walled partitions concentrically arranged therein in contact with each other at intervals to form a circular series of separating compartments between each of the said partitions and the contacting inner or outer one, each of said compartments having skim-milk openings in two of its walls and also cream-openings in two of its walls and said openings providing jointly separate outward and inward flow passages through adjoining innerV and outer compartments, substantially as described.

2. In a centrifugal liquid-separator, two or more vertical walled partitions of angular cross-section concentrically arranged in contact with each other at intervals to form a circular series of separating compartments between them, each of said compartments having skim-milk openings in two of its walls and also cream-openings in two of its walls and said openings providingjointly separat-e outward and inward flow passages through adjoining inner and outer compartments, sul)` stantially as described.
